Amiga 500 PSU Tester

Amiga 500/500+/600/1200 power supply unit (PSU) automated tester. Forces a constant current from the power supply and measures voltage levels and ripple. Results are displayed in real time on a digital OLED display. The tester features an aluminum heat sink to perform long-term tests. Square DIN5 plug matching the original Amiga 500 PSU pinout.

Check it before it's too late

Power supply failures are among the most common problems among retro Amiga 500/500+/600/1200 systems. An Amiga 500 PSU failure can lead to expensive repairs, or even render the entire system useless. This is specifically why we have designed the Amiga 500 power supply tester. It runs a thorough test, minimizing the risk of damage due to an ageing factory power supply.

Voltage, current, ripple

The Amiga 500 tester measures the primary +5V DC output voltage and ripple at a constant current of roughly 400mA...500mA. Secondary voltages (+12V DC, -12V DC) are measured at a lower current, typically 50...150mA. Measurement results are updated on a digital OLED display in real-time, allowing a live evaluation of the power quality.

Long-term testing

The power supply tester has an aluminum heat-sink allowing to dissipate excessive power and perform long-term testing. It's designed to work both as a quick diagnostic tool, and for long-term stability tests.
